Abstract Electrophoretic analysis has shown populations of F. heteroclitus to possess variants at four enzyme-coding loci: Ldh-B, Mdh-A, Gpi-B, and Pgm-A. Based on the phenotypic distribution in the F1 generation, each variant segregates as an autosomally inherited codominant allele. A pairwise comparison of the expected phenotypic classes among these loci showed no evidence of strong linkage; however, weak linkage could not be ruled out. Despite the considerable genetic divergence of populations from the geographical extremes of this species, offspring resulting from crosses between individuals from these localities show viabilities similar to those found for crosses of local populations.
